(2ND GENERATION) FM-RX2-XXX Functional description: The TX2 transmitter module is a two stage, SAW controlled FM transmitter operating between 2V and 6V and is available in 433.92MHz and 418.00 MHz versions. The 433.92 MHz unit is type-approved to ETS 300-220 for European use and delivers nominally +9dBm from a 5V supply at 12mA, while the 418.00 MHz unit has MPT 1340 type-approval for U.K. use and delivers -3dBm from a 5V supply at 5mA. Both modules measure 12 x 32 x 3.8 mm. The RX2 module is a double conversion FM superhet receiver capable of handling date rates of upto 40kbit/s. The SIL style RX2 receiver measures 17.5 x 48 x 4.5 mm. It will operate from a supply of 3-6V and draws 14mA when receiving. A fast-acting carrier detect and a power-up enable time of less than 1ms This allows effective duty cycle power saving and a -107 dBm sensitivity. This, combined with a SAW front-end filter results in an excellent RF performance and EMC conformance.
